Self-reproduction of the SR loop in finite space

At first the SR loops show their regular growth pattern. However,
when the opposite edges of the colony collide with each other due to
the periodicity of space, the irregularity of the emerging situations
leads to a failure of the loops' function, so that their
self-reproductive behavior halts. Eventually, the entire space is
filled with static patterns including corpses of loops. After that, no
changes can happen in this world any more.
